HURRRRRRRRRRRRRRAHHHHHHHHHH
Got it working
Installed ZW mod using installer, created new directory when told it did not exist, then dragged it to program files and was asked if I wanted to replace existing folder, yes to all and now it runs.
I did a clean install of original game.
now to have fun.
Many thanks Zeewolf
Happy New Year to all
Cheers
